Expert Solution
Step 1

Given: The mass of the person is 78.5 kg.

           The mass of the elevator is 606 kg

           The acceleration is 2.45 m/s2

To determine: (a) The free body diagram

The forces that act on the system are

1. Tension, that acts in upward direction. 

2. The gravity, it acts in the downward direction. 

3. The force, Ma that acts in the direction of elevator, downward.
